Application filed July 21, 1914. Serial No. 852,222.

To all whom it may concern:

Be it known that 1, Moses Loon, a citizen of .the UnitedStates, and aresident of the town of Ellington, near the village of Sin clairville,in the county of Chautauqua and State. of New York, have inventedcertain new-.and. useful Improvements in Vehicle- Brakes, 01'' which thefollowing is a spec1fication, reference being had to the accompanyingdrawings, forming part of this spec1fication.

My invention has for its object to provide a vehicle with an emergencybrake so arranged that the same. may be instantly thrown into operationwithout straining any part of the vehicle.

Another object of my invention is to pro vide. a vehicle with anemergency brake, which when thrown into working position will raiseandsupport the rear. end of the vehicle, the load being carried upon twobrake shoes which are dragged upon the ground. With these and otherobjects in view the present invention consists in the combination andarrangement of parts as will be hereinafter more fully described andfinally pointed out in the appended claims, it being further understoodthat changes 1n the specific structure shown and described may be madewithin the scope of the claims, without departing from the spirit of theinventiOh.

In the accompanying drawingsformipg a part of this specification, and inwh ch like numerals of reference indicate similar parts in the severalviews: Fi re 1 shows a side elevational view of a vehicle provided witha brake embodying my invention. Fig.

4 2 is' an enlarged sectionalviewof the housing show'i'ngthe detent inoperative osition. Fig. 3 shows aperspective view 0 the detent. Fig. 4shows a bottom view of Fig. 1. Fig. 5 is a section on line 5, 5, ofFig.4.

Fig. 6 is a section on line 6, 6, of Fig. 4. Fig. "7 shows a detail ofthe drag bar and its connectedtrunnions'.

' In the accompanying drawings the letter A designates a vehicleprovided with a front axle B, and a rear axle C, provided with thevehicle wheels a.

Secured to the bottom 10, of the vehicle is a housing 11, the sides ofwhich are provided with parallel extending channels or grooves 12. Thebottom 13 of the housing is provided with an opening 9. This housing issecured to the underface of the bottom 10 of the wagon or vehicle, asshown in Fig. 2.

Slidably held within the housing 11, is a drag bar 14, the forward endof which is provided with the trunnions 15 and eye 16 which extends fromthe trunnions, as shown in Fig. 7 These trunnions 15 are arranged toslide within the channels or grooves 12,

these channels ending in the stop shoulder b, these stop shoulders I;being engaged by the trunnions and limiting the excursion of the dragbar. At the remaining end each drag bar 14 ends in a brake shoe -17,these brake shoes preferably being provided with spurs 0, shown inFig. 1. These spurs however, are not necessary.

Near its forward end the drag bar 14 is provided with a socket 18 andnear its opposite end with an eye 19. As shown in Fig. 4, these dragbars 14 and housings 11 are disposed in sets of twos, though each worksseparate and independent. Secured to each eye 19 is a coil spring 20,these springs being secured at their other ends to a suitable eye 21fixed to any suitable part of the vehicle.

Secured in any suitable manner to the rear axle C of the vehicle A is acollar 22, each collar forming part of a supporting bar 23, eachsupporting bar at its other end being pivotally secured to one of theeyes 19 extending from the brake shoes 17. These collars 22 are looselysecured to the axle C and each bar 23 is arranged to swing from ahorizontal position downward into a vertieal position. The length ofeach supporting bar 23 is greater t an the radii o the rear wheels for apurpose to beset forth later on.

Held. within a bexihg 24 seclii'ed. adjabent to the housing 11 is areleasing member in the form of an L-shaped having alon I leg 25 and ashort leg 26, the short leg 2 ending in the wedge-shaped detent 27.shown in Fig. 5 the member 25 is provided with a collar 28 and workingagainst this collar is a spring 29 to normally force this member 25which is provided with the head 30 upward. In its upward position, thedetent 27 is within the socket 18 to ne-1d the drag bar 14 in aretracted position. Held between the sides of the housing" '11 is a pin31' carrying a shive 32 over which passes a liable member 30 having oneend secured to the eye 16 and the oppb'site end coiled within an opening'34: formed within the bottom 10, this opening normally being closed bymeans of the plate 35. As shown in 5, the housing 11 is provided withears 8 through which suitable bolts/Z pas's which are employed to holdthe housing to the vehicle.

Secured to a suitable shackle 37 secured to the vehicie are two similarbrace 'r'odfs 3 8-, these brace rods having their outer ends secured tothe eyes 19 forming a part of the brake shoes 17, this constructionbeing best shown in Fig. 4. I

As explained, these emergency brakes are secured to a vehicle in setsoftwos.

The operatien is as follows: On setting the brake members, the drag bars14 are shoved into the housings against the tension of the springs 20until the "detent 27 finds a setting within its socket 18. lhe roundedend of the trunnions 1' 5 insures the del'iiint being forced downwardagainst the tension of the spring 20 in finding its way into the socket.In referringto Fig; 2 it will be noticed that the distancebetween thetop of the housing 11 and the bottom 13 there of is approximately thatof the trunnion-s 15, but that the housing gradual-1y 'widens verticallytoward the outer end so that there is ample room for the eye 19 andspring 20 within the largest end of the housing.

In the retracted position of the dlfag bars, as shown in Fig. 1' thesupporting bars 23 are held in a horizontal position, the bars 14bein-gheld; against the tension ofthe springs 20 As soonas it is foundnecessary to bring the. emergency brake into'play, it. is simplynecessany for the operator to press his foot upon the head 39,whichjresuits} in the detent escaping. from its socket,

Inthis position, the supporting bars 23 are in a vertical position, asshown in Fig. 1 in dotted lines, in which position the rear part of thevehicle is supported and carried by the bars 23 the rear wheels abeinfinitimfi fihinth giouhd. lit may. be readily understood then thatwith the brake shoes in friction l contact wi h th earth that theadvance 6 the vhiel wil be instantly checked and finally entirelystopped.

order to draw the bars 1 1 into the housi again the operator simplygrabsthe pli; ab e mem'er 34 and pulls upon the same until the detentagain finds seating within the socket.

By this means the vehi'cleis provided with an emergeneybrake which issimple of construction and positive of opbrati'oh, and which can bethrown into working. position with ease, ah'cuiaby and despathhi Ha'vin'thus described my said invention what I c aim as new and desire tosecure by U. 8.
